I got my first bike from a family. A 1975 XS 650 B. It has been sitting in a storage unit for at least 5 years and wasn't running due to a stuck piston. I tried to free the pistons but ended up having to dismantle the upper part of the motor. After disassembling the upper and freeing the stuck left piston, I determined that the lower was needing to be examined, cleaned and rebuilt (debris and crusty oil residue and gasket material noticed inside crank shaft area).
So here is where I am in the process. I'm waiting for a good day to separate the lower housing. Only thing I have left it to remove the 18 bolts that hold the casing together and separate the case.
My question is this. Since I will have the motor apart, what modifications would be a good thing to do at this stage. I already plan on swapping out the 5th gear for the overdrive gear but not sure what other modifications I should do to improve performance of the motor.
Any other suggestions would be appreciated.
